1. import os
   
2. 
   
3. def search_file(start_dir, target):
   
4.         os.chdir(start_dir)
   
5. 
   
6.         for each_file in os.listdir(os.curdir):
   
7.                 if each_file == target:
   
8.                         print(os.getcwd() + os.sep + each_file)
   
9. 
   
10.                 if os.path.isdir(each_file):
    
11.                         search_file(start_dir, target)
    
12.                         os.chdir(os.pardir)
    
13. 
    
14. start_dir = input('请输入待查找的初始目录：')
    
15. target = input('请输入需要查找的目标文件：')
    
16. search_file(start_dir, target)

完全按照小甲鱼老师的代码打了一遍，为何还是死循环？？

1. 请输入待查找的初始目录：F:\\2
   
2. 请输入需要查找的目标文件：a.txt
   
3. Traceback (most recent call last):
